At Specialty Gear Drives, we specialize in the repair, rebuild, and in-house manufacturing of Rossi gearboxes
All Fields Must Be Filled Out
At Specialty Gear Drives, we specialize in the repair, rebuild, and in-house manufacturing of Rossi gearboxes — from compact gear motors to heavy-duty industrial reducers. Our Timken-certified technicians restore Italian-precision Rossi equipment to better-than-OEM condition, fast and cost-effectively.
Rossi gear drives are built to thrive in the toughest industrial environments — but when variables outside their design parameters intervene, even Italian-precision engineering requires expert repair. Specialty Gear Drives has the tooling, certifications, and in-house manufacturing capability to restore any Rossi unit to full performance.
We handle the complete Rossi product range — gear reducers, gearmotors, planetary units, and custom configurations — with the same attention to dimensional accuracy that Rossi’s own engineers in Modena demand. When OEM parts are unavailable, we manufacture them ourselves.
From compact gearmotors to large-scale industrial reducers, we service the full Rossi product catalog across all mounting configurations and gear profiles.
Rossi’s workhorse parallel-shaft and foot-mounted helical reducers used across material handling, conveying, and general industrial applications. We restore all internal gear profiles to original tooth geometry and surface finish.
Rossi planetary reducers delivering high torque-to-size ratios for demanding applications. We fully disassemble, measure, and rebuild every carrier, sun gear, ring gear, and planet assembly to exact OEM specifications.
Right-angle Rossi drives combining bevel input stages with helical secondary reductions. We manufacture bevel gears in-house using reverse engineering or existing blueprints when OEM replacements are unavailable.
Integrated Rossi gearmotor assemblies used in food processing, material handling, and packaging applications. We service both the mechanical gear drive and motor interface components as a complete assembly.
Large-frame Rossi units serving mining, cement, steel, and marine applications. Our gear cutting center produces replacement gears up to 20 feet in diameter — fully meeting the torque and hardness demands of these extreme-duty applications.
Rossi’s history of producing customized solutions for specific customer requirements means we often encounter unique configurations. Our reverse engineering team documents and replicates any custom Rossi unit regardless of OEM support status.
Every Rossi gearbox receives the same disciplined, documented rebuild — from the initial cleaning through final load testing and 24-month warranty certification.
We arrange no-cost nationwide freight pickup. Your Rossi unit is logged and assigned to a dedicated technician immediately upon arrival, with full disassembly beginning the same day.
All components are cleaned in our industrial parts washer using an organic solution. Each part is then individually measured and documented — gears, shafts, bearings, seals, housing bores, and carrier assemblies.
We identify and document the exact cause of failure — not just the damage. This ensures the same failure mode doesn’t recur after the repaired Rossi unit returns to production.
Worn Rossi gears are manufactured on-site to OEM specifications — matching original Rockwell and Brinell hardness ratings. Helical, bevel, planetary, and worm profiles all produced in our CNC gear cutting center.
Reassembly uses Timken-certified bearings installed via liquid nitrogen thermal process. All new seals, gaskets, and a high-temp polymer coating on the housing complete the rebuild to better-than-OEM standard.
Every rebuilt Rossi gearbox runs a full six-hour load test monitoring vibration, temperature, and leak-tightness before certification. Units passing all checks ship with our 24-month production warranty.
